1Password by AgileBits is a an incredible tool for keeping your data safe. More than just a password manager, 1Password allows you to encrypt and organize a wide range of data (website passwords, non-web digital accounts, credit/debit card numbers and financial account details, software licenses, and files containing confidential information.

Those features are all well and good, but the biggest feature is 1Password’s ability to keep all that data secure in the face of brute force attacks – the kind of attacks where a piece of software simply tries combination after combination of possible passwords. Password cracking software that rely on such attacks can easily try thousands of potential passwords each second.

To find out whether or not 1Password can withstand such attacks, AgileBits tested one 1Password against John the Ripper, one of the most well-known password cracking tools.
